Abstract
In this article, a comparative assessment of the technical and economic efficiency of rational combined steel trusses with typical trusses according to DSTU is considered. New rational constructive combined forms of covering systems (roof trusses) have been developed for spans of 18, 24 and 30 m, with less material consumption and labor intensity compared to existing analogues. It is shown that the mass of such rational combined steel trusses with a span of 18 m is less than a typical one by 13% to 16.5% depending on the value of load, for a combined truss with a span of 24 m the mass is less by 20.5% to 25%, and for a 30 m - from 12.5% to 17%. The results of the evaluation of the technical and economic efficiency are presented. The main criterion for the economic efficiency of constructions is general costs. A comparison of the technical and economic efficiency proves that our proposed option provides a significant saving of material and labor resources.Widespread implementation can provide a significant economic effect, which is important in the conditions of post-war reconstruction of Ukraine.
